- Audi is proud to present a world first - the first
twelve-cylinder diesel engine in a series passenger car. This
six-litre V12 makes its debut in the Audi Q7. It produces a
colossal 500 PS and 1,000 Nm of torque. With this engine Audi
has opened a new chapter in diesel history.
The V12 TDI is reminiscent
of the engine featured in the new R10 Le Mans racing car - it
catapults the driving performance of the Audi Q7 into the
echelons of top-class sports cars.
The car
sprints from 0 to 100 km/h in just 5.5 seconds, and has
an electronically governed top speed of 250 km/h.
Maximum torque is available from just 1,750 rpm. The
high-tech diesel engine, with the world's first 2,000
bar Bosch Common Rail system, provides the
high-performance Audi SUV with superior power reserves
in any situation.
The impressive sound of
the new Audi is provided by the ultra-modern piezo-injection
system. The V12 TDI transmits this power through a new
six-speed tiptronic gearbox to the quattro permanent
four-wheel drive system.
Although the V12 TDI
belongs to the Audi V-engine family, this model features
a special cylinder angle of 60° - perfect for this
engine type. Apart from the light and highly durable
crankcase, a further highlight is the new chain drive
assembly. This includes the two newly developed
high-pressure pumps in the common rail injection system.
Up to 2,000 bar of
pressure is kept within the twelve piezo injectors - a
further technological breakthrough. Both performance and
efficiency are optimised by this high injection
pressure, and the running smoothness also remains
excellent. Exhaust emissions are also low.
The twin-turbo
V12 TDI conforms to the Euro 5 emissions class which should come into
force in 2010. Fuel consumption is only 11.9 litres per 100 kilometres.
With the high-tech twelve-cylinder engine using TDI technology, the
diesel pioneers at Audi have opened new horizons in motoring.
